Discipline Quote by Terrie Moffitt
“Although self-control is inheritable and does run in families and has a genetic component, it's more like height than anything else. Height is one of the most strongly inherited traits that human beings have and yet when we improve the nutrition of the population everybody gets taller. So you can shift the entire population by an effective intervention.”
About This Quote

In simple terms: Genes set a baseline; environment can raise it.
